TO LL WHOM IT MAY CONCERN:

Be it known that I, B. J. WATSON, of Troy, in the county of WalworthJan'd State of Wisconsin, have invented a new and improved Stove-Attachment} and I do hereby declare that the following is a full, clc'ur, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had tothe accompanying drawings, forming part of this specification.

Thisinvention relates to a new and improved method of constructing antler-ranging the flues oi parlor and box-stoves, whereby a greater radiating-surface for heat is presented within a smaller compass, so as to occupy less room. It consists of a chamber above the fireox between the two plates which form the top of the stove, separatedinto'passages or flues by partitions running longitudinally through the same. It consists also of a pipe passing nearly around the stove, and on the lower plate of the top of the same, one end of the same opening into one Qof said chambers, and the other end of the same opening-into other of said chambers, so that the smoke and heat passlthrough the entire iength of one of said chambers into and through the entire length of said pipe,- and into and. throughthe other of said chambers, before passingout into the chimney, whereby a great radiating surface is presented and a great saving-of heat eflectedf In the accompanying plate of drawings- Figure 1 is a plan view of my invention.

Figure'2 represents a vertical longitudinal section of the same, taken in the line a: 9;, fig. 1.

Similar, letters of reference indicate corresponding parts. v

S is the stove; D are ridges or strips on the plate K; K is the lower plate of the top of the stove; T is the upper plate orcover; C and D are partitions on plate K, dividing the space between the upper and lower plate of the 't'op of the stove into the chambers G and H. F is a pipe passing around on the lower plate of the top of the stove'opening intoithe chambers G and H. B is an opening in plate K. A is an opening or flue in plate or cover T, communicating with the chimney. a is the damper. The arrows show the direction of the draught.

Upon any parlor or box-stove S'is a top, composed of the two plates K and T, having a suflicicnt distance between them for the pipes F, and for the passage of the smoke and heat between them. The upper plate is a cover having sides, so as. to form the sides of thech amber between the plates K and T, and to cover and proteot the pipes F. Said plate or cover T is secured to the plate K by suitable hinges, so that the same may be moved at any time to clear or repair the flues, so that when ploscd it forms the top of the chambers G and H. Upon said plate K, either cast as a. part of the same, or rigidly scoured thereto, arethe partitions C and D, secured to an end-piece or the front of the stove, so'as to form the chambers G- and H, as shown in the drawing, fig. 1, Through the .plate K, and opening directly into the fire-box and "into the chamber H, as shown,

the partitions: l being bent around the same on one side, as shown, is an opening or passage, B. Through said plate K, and opening also into the fire-box, and so as'to open into the chamber G near the back end of the stove,

as shown is'another opening, A. Through the partitions D, near the front of the stove, and opening into the chamber G, is a pipe, turning by an elbow and passing along theoutsi'de of chamber G on the plate K entirely I around the back end of both the chambersG and H, turning with suitable elbows, and along on the outside of the chamber H, where it opens into the same near thedront of thestove. Upon the plate K, and so as to close. either ofthe openings A or B, or so as when one is shut the other is open, is a damper, a, provided with a suitable passage through the stove, as shown. I The cover or plate T is provided at the sides and top with suitable v and damper a, substantially as shown and described, and for the purposes set forth.

openings to permit the 'escapeof heat into the room, andalso for ornament.

Theoperation is such, as will be seen from the drawing,that by opening the opening 13, and closing the opening A, the drought will take the direction shown by the al'rows,.the Home and smoke passing forwards to the openingof the pipe F, and through the entire length of the same, around the chambers H and G into the chamber Gr, and through said chamber into the pipe A in the cover or top plate '1, and out into the chimney.

Gonstructed as above shown and described, it constitutes a cheap and compact hue-attachment for stores, the advantage of which is that it presents a very large surface for radiating heat, occupying very small space.-

Y I claim as new, and desire to secure by Letters Patent 1. A flue-attachment for stov'es, consisting of the chambers G'and H, and, pipe F, substantially as shown and described, and for the'purposes set forth.

2. The chambers G and H, in combination .witha stove, S, and pipe F, and damper a, substantially as shown and described, and for the purposes set forth.

3. The chamber G, in combination withthe pipe A, and the chamber H, in combination with the'pipe B, I
